MV breaking techniques

The ability to break current in an electrical circuit is essential in order to guarantee the safety of people and property in the case of faults, as well as to control the distribution and use of electrical energy.
The aim of this Cahier Technique is to detail the advantages, disadvantages and applicational fields of past and present Medium Voltage breaking techniques.
Having defined the currents to be broken and discussed breaking on a theoretical level, the author goes on to present breaking in air, oil, and in SF 6 , finishing with two comparative tables.
To date, breaking using electrical arcing remains the only viable solution, whether in SF 6 or under vacuum; it requires expertise that this Cahier Technique invites you to share.
